Pick Best Solar Panel Connectors And Cables Beyond 2020

Introduction to Solar panel connectors and cables

Do you want to know about MC4 connector (male connector & female connector) and MC4 extension cable (8ft, 15ft, 30ft, 50ft, and 100ft)? Here, in this post, you will find complete details about these connectors and cables and their uses.

You must have noticed that most of the high power solar modules are manufactured with the help of wire leads, and they consist of MC4 connectors on the ends. Earlier, solar modules were built with a junction box on the back that needed a professional to attach wires manually to the positive and negative terminal posts. However, this method is still used, but becoming unpopular slowly.

Today’s solar modules use the MC4 connectors because they make connecting solar panels much simpler and faster. MC4 connectors are available in both male and female types and can be designed to snap together.

They also fulfill the needs of the National Electric Code as they are UL certified. As MC4 connectors include a locking mechanism, they do not get unplugged and are ideal for the outdoor environment. These connectors can easily separate, but needs a special MC4 unlocking tool.

When it comes to connecting two or more solar modules to wire in series, MC4 connectors can be used. On the other hand, parallel wiring needs the positive leads to connect together, and the negative lead to connect together. This process can increase the current at max power that keeps the voltage constant. For instance, your modules are rated for 8 amps Imp, and 18 volts Vmp.

If you want to connect two of them in parallel, your total amps might be 16 amps Imp, and the voltage might remain at 18 volts Vmp. When it comes to wiring two or more modules in parallel, you will need additional equipment.

If you are using two modules, the easiest way is to use MC4 multibranch connectors. You cannot connect two male connectors or two female connectors; hence you need multibranch connectors to accomplish that. There are two main multibranch connectors.

The first one accepts two male MC4 connectors on the input side and includes a male MC4 connector for its output. The next one accepts two female MC4 connectors and includes a female MC4 connector for its output.

MC4 Extension Cable and Its Uses

It is quite obvious that you might get confused by the MC4 extension cables, especially when you never worked with solar modules before. The first thing that you should know is that they are expensive. No one wants to buy an expensive cable and then realize that the length is too short after cutting.

You cannot return cut cables, so how will you choose the appropriate length and how will you use them to connect your panels together.

A cable is very similar to an electrical extension cord. Like an extension cord has a male plug on one end and a female on one other, this extension cable also has a male connector on one end and a female connector on the opposite end. These cables come in different lengths from 8 feet to 100 feet.

When it comes to buying the right type of MC4 extension cable, you have a number of options available to select from. There are so many online portals available that offer different types of connectors, including parallel branch connectors at great prices. Simply find the right online shop and place your order online with confidence.
